Your Symphony soundbar is capable of HDMI Passthrough. HDMI Passthrough send video and audio signals from a HDMI source such as a Blu-ray player, HD Set Top Box or game console to the soundbar via a HDMI cable. The soundbar plays the audio from the HD source through its own speakers and sends the unaltered video signal to a TV via a second HDMI cable.
Note
Once the setup is done, press the button repeatedly on the soundbar or the "SOURCE" button on the soundbar remote control to navigate to either HDMI IN 1 or HDMI IN 2.
On the TV, using the TV remote control change the Source/Input to the HDMI input that the soundbar is connected to.
Do note that only 1 HDMI input is usable at a time.
